dens, which are uncovered during the recess of spring 

 tides at Herm, is enormous ; in one of these heaps he 

 counted more than 2000 shells, half of which were 

 Tapes pullastra, and the other half T. virgineus, with 

 a few T. aureus and Psammobia vespertina. The 

 pieuvres are used in France as a bait for conger eels ; 

 and, according to Bouchard- Chantereaux, they are 

 caught at neap tides with a piece of dogfish, and dragged 

 out of their holes at low water of spring tides with a 

 pole-hook. Cantraine says the Octopus is dreaded by 

 the Italian divers and bathers. The water is admitted 

 freely to the gills through a large opening between the 

 mantle and the head on the underside, and is expelled 

 through the funnel. When this creature is at rest, the 

 respiration is regular and resembles the action of a pair 

 of bellows. 



It is the Sepia octopodia of Linne, and Polypus anti- 

 quorum of Leach. O. tuberculatus of De Blainville is 

 apparently a mere variety.

 Arm-suckers arranged in a single row. 



Aristotle, in his History of Animals (A. 0. 15), dis- 

 tinguished this kind from Octopus (TrokvTrovs) by the 

 above character. The difference between them is, per- 

 haps, not less than that which separates Ommatostrephes 

 from Loligo. 



Menke, Steenstrup, and Morch have spelt the name 

 Heledone, supposing that the first letter was aspirated ; 

 Gaza and Clark give Eledona.
